The credit carry forward for the North Dakota Research and Experimental Expenditure tax credit is a statutory provision allowing businesses to preserve unused tax credits for up to fifteen years. This mechanism ensures that companies engaged in innovation can utilize the full value of their research incentives against future income tax liabilities as their profitability grows.

Under the North Dakota Century Code § 57-38-30.5, the Research and Experimental Expenditure Tax Credit is established as a nonrefundable incentive designed to stimulate technological advancement within the state’s borders. Because the credit is nonrefundable, a taxpayer may find that their total earned credit for a given year exceeds their actual income tax liability for that same period. To prevent the loss of this earned benefit, the law provides a sophisticated temporal movement system: a mandatory three-year carryback followed by a fifteen-year carryforward window. This extended duration is particularly critical for sectors with long development cycles, such as the energy, agriculture, and manufacturing industries that form the backbone of the North Dakota economy. By allowing a fifteen-year horizon, the state mitigates the fiscal risk associated with multi-year research projects that may not yield taxable income for several cycles after the initial expenditures are incurred.

Statutory Basis and Legal Framework

The foundational authority for the North Dakota Research and Experimental Expenditure Tax Credit is codified in N.D.C.C. § 57-38-30.5. This section of the law provides the comprehensive definitions and procedural requirements for claiming the credit, as well as the specific limitations on how it may be carried between tax years. The North Dakota Legislative Assembly has structured this credit to largely mirror the federal research credit found in Internal Revenue Code (I.R.C.) § 41, yet it maintains distinct state-specific nuances to ensure the economic benefit remains localized.

The law differentiates between taxpayers based on the historical timeline of their research activities. For those who first earned or claimed the credit in a taxable year beginning prior to January 1, 2007, the state imposes an annual maximum credit limit of $2 million. Crucially, any credit earned in excess of this $2 million cap for such taxpayers is permanently disallowed and may not be carried back or forward to any other taxable year. Conversely, for taxpayers who began their research activities after December 31, 2006, the credit is generally uncapped, provided the expenditures meet the qualifying criteria and are performed within the state of North Dakota.

Core Definitions and Federal Alignment

The North Dakota tax commissioner provides guidance that “qualified research” and “qualified research expenses” (QREs) for state purposes share the same definitions as those found in I.R.C. § 41(d) and § 41(b), respectively. However, the state introduces a critical “North Dakota Nexus” requirement: the research must be conducted entirely within the state, and the expenses must be attributable to North Dakota activity. This means that while a company may follow federal documentation standards, they must segregate their accounting to isolate costs incurred within North Dakota’s jurisdiction.

The “base amount” calculation also follows the federal methodology under I.R.C. § 41(c) but excludes any research conducted or sales generated outside the state of North Dakota. This ensures that the incentive is proportional to the taxpayer’s commitment to the local economy. Furthermore, the statute mandates that qualified research expenses may not exceed 50% of the base amount in the calculation of the regular credit, which acts as a stabilizer for the credit’s growth relative to the company’s historical performance.

Mechanics of the Carryback and Carryforward Provision

The North Dakota R&D tax credit is not a “use-it-or-lose-it” incentive for the current year. The Office of State Tax Commissioner outlines a mandatory sequence for the application of unused credits. When a taxpayer’s determined credit exceeds their actual liability, they must navigate a specific temporal path to utilize the excess.

The Mandatory Three-Year Carryback

Before a taxpayer can carry a credit forward to future years, they must first apply the excess unused credit to each of the three preceding taxable years. The law requires that the credit be carried first to the earliest of the three years and then sequentially to each successive year. This carryback provision acts as a liquidity mechanism, allowing companies that were profitable in previous years to recover taxes paid through an amended return.

The administrative timeline for this process is strict: a claim to carry back the credit must be filed within three years of the due date (or extended due date) of the tax return for the year in which the credit was originally earned. Failure to file within this window results in the loss of the carryback opportunity, though the credit may still be eligible for carryforward.

The Fifteen-Year Carryforward Window

If the credit is not fully absorbed after the three-year carryback period, the remaining balance may be carried forward for up to fifteen years. This extended period is one of the most generous in North Dakota’s tax code, acknowledging the high-risk, high-cost nature of modern research and development.

The fifteen-year window allows companies in cyclic industries, such as oil and gas or agriculture, to bank credits during downturns or heavy investment years and apply them when commodity prices recover or new products reach the market. The credit is applied year-by-year against the liability until exhausted or until the fifteen-year term expires.

Credit Application Hierarchy

North Dakota administrative rules provide an “ordering rule” for how various tax credits must be applied to a return. This is designed to ensure taxpayers do not accidentally let credits with more restrictive carryover rules expire while using credits that have longer windows.

1. Non-Carryover Credits: Credits with no carryback or carryforward provisions must be used first.
2. Carryback Credits: Credits with carryback provisions (like the R&D credit) are applied next.
3. Carryforward Credits: Credits with carryforward-only provisions are applied last.
4. Priority Within Categories: If multiple credits have the same priority, the taxpayer may apply them in the order that is most beneficial to them.

Calculation Methodologies and Impact on Carryover

The amount of credit available for carry forward is dictated by the calculation method elected by the taxpayer. Since 2019, North Dakota has offered two distinct pathways: the Regular Method and the Alternative Simplified Computation (ASC) Method.

The Regular Calculation Method

The regular method uses a tiered percentage structure based on how much the taxpayer’s current-year North Dakota QREs exceed their state-specific base amount.

• Tier 1: 25% of the first $100,000 of excess expenses.
• Tier 2: 8% of all excess expenses over $100,000.

The regular method is generally advantageous for established companies with stable R&D spending patterns relative to their gross receipts. For companies that started research before 2007, historical tiered rates applied—such as 7.5% in 2007, 11% in 2008, and 14.5% in 2009—before the rates stabilized at the current 8% for the second tier.

The mathematical formulation for the Regular Credit (C_R) is:

C_R = (0.25 × min(E, 100,000)) + (0.08 × max(0, E – 100,000))

Where E represents the excess QREs over the base amount.

Alternative Simplified Computation (ASC) Method

Taxpayers may annually elect the ASC method, which uses a three-year lookback of QREs rather than gross receipts to determine the base. This is often more beneficial for high-growth startups or companies with fluctuating sales.

Under the ASC method, the credit is calculated as:

• 17.5% of the first $100,000 of “alternative excess” expenses.
• 5.6% of alternative excess expenses over $100,000.

“Alternative excess” is the amount by which current North Dakota QREs exceed 50% of the average QREs for the three preceding years. If the taxpayer had zero QREs in any of those three preceding years, the rates are adjusted to 7.5% for the first $100,000 and 2.4% for the excess.

Transferability and Monetization for Small Businesses

A unique feature of the North Dakota R&D tax credit is the ability for certain small, innovative firms to sell or transfer their unused credits. This is a critical liquidity tool for companies that have significant R&D costs but no tax liability against which to apply a carryforward.

Eligibility for Transfer

To be eligible to sell, transfer, or assign credits, a company must be certified by the North Dakota Department of Commerce as a “qualified research and development company”. The certification requirements (via Form SFN 58638) are rigorous:

1. Primary Sector Business: The business must be certified as a “primary sector business,” meaning it adds value to a product, process, or service through knowledge or labor, resulting in the creation of “new wealth” (sales to out-of-state customers or replacing previously unavailable local services).
2. New Research Activity: The taxpayer must have conducted qualified research in North Dakota for the first time after December 31, 2006.
3. Revenue Threshold: The business must have annual gross revenues of less than $750,000.
4. Entity Type: This provision is generally limited to individuals, C corporations, estates, or trusts.

Transfer Limits and Procedural Guidance

A qualified company may transfer up to $100,000 of its unused tax credit over any combination of taxable years. This transfer must be documented using Form CTS (Credit Transfer Statement), which must be filed within 30 days after the transfer agreement is executed.

The purchaser of the tax credit inherits the same carryforward rights as the original holder but is subject to two major restrictions:

• No Carryback: The purchaser may not carry back the purchased credit to prior tax years.
• No Resale: The original purchaser is prohibited from selling, assigning, or otherwise re-transferring the credit.

Administrative Compliance and Local Guidance

The North Dakota Office of State Tax Commissioner provides specific procedural mandates for claiming and maintaining the research credit. Because the credit is permanent and involves significant carryover potential, documentation is paramount for defending against future audits.

Filing Procedures

Taxpayers must claim the credit on their respective state income tax forms:

• Individuals: Use Schedule ND-1TC.
• C Corporations: Use Form 40, Schedule TC or Schedule CR.
• Passthrough Entities (S Corps/Partnerships): The credit is calculated at the entity level and reported to owners on Form 60, Schedule K or Form 58, Schedule K, respectively.

Regardless of the form used, the taxpayer must attach a detailed schedule or worksheet showing the computation of the credit. For carryforward amounts, the taxpayer must maintain a record of the original year the credit was earned and the amounts used in each subsequent year to ensure the 15-year limit is not exceeded.

Audit and Documentation Standards

The Tax Commissioner has the authority to audit returns to verify the correctness of the transferred tax credit for up to four years after the date of assignment. For non-transferred credits, standard statute of limitations for state audits apply, but taxpayers are advised to retain documentation for the entire duration of any carryover period.

To satisfy the “four-part test” adopted from federal law, the state revenue office expects documentation that demonstrates:

• Technological Nature: Reliance on principles of physical, biological, or computer science.
• Elimination of Uncertainty: Records of the technical challenges the research sought to overcome.
• Process of Experimentation: Evidence of modeling, testing, and systematic trial-and-error.
• Permitted Purpose: Proof the research aimed to improve the functionality or quality of a business component.

Economic Context and Strategic Utilization

The Research and Experimental Expenditure Tax Credit is a vital component of North Dakota’s strategy to diversify its economy beyond raw commodity extraction. The state’s economic landscape is heavily concentrated in energy (18% of GDP) and agriculture (4% of GDP), both of which are highly susceptible to market volatility.

Sectoral Impact

By offering a robust 15-year carryforward, North Dakota provides a “tax shield” for companies in these volatile sectors. During years of low commodity prices or high initial R&D investment, companies accumulate credits that significantly reduce their tax burden when profitability returns.

The Tax Commissioner’s 2024 reports show modest gains in the manufacturing and energy sectors, indicating that the innovation ecosystem supported by these credits remains resilient despite inflationary pressures.

Interaction with Federal Policy

Because North Dakota’s income tax calculation begins with federal taxable income, the state is automatically affected by federal tax legislation such as the One Big Beautiful Bill Act (OBBBA) signed in 2025. However, North Dakota specifically decouples its state tax credit calculations from federal credit changes, meaning that state-level R&D credits remain a stable and predictable incentive regardless of shifts in federal tax law.

Comprehensive Multi-Year Carryover Example

To demonstrate the application of N.D.C.C. § 57-38-30.5 in a practical business scenario, consider “Dakota Ag-Tech Solutions,” a mid-sized firm developing robotic harvesting equipment.

Year 1 (2024): Credit Generation and Carryback

In 2024, the company incurs $800,000 in North Dakota QREs. Their base amount is $500,000, resulting in $300,000 in excess expenses.

Step 1: Calculate the Credit

• 25% of the first $100,000 = $25,000
• 8% of the remaining $200,000 = $16,000
• Total Credit Earned: $41,000.

Step 2: Current Liability Offset

• The company’s 2024 tax liability is $10,000. They use $10,000 of the credit, leaving $31,000 unused.

Step 3: Mandatory Carryback

• The company must carry the $31,000 back to 2021, 2022, and 2023.
• 2021 Liability: $5,000. Refund generated: $5,000. (Remaining: $26,000).
• 2022 Liability: $8,000. Refund generated: $8,000. (Remaining: $18,000).
• 2023 Liability: $4,000. Refund generated: $4,000. (Remaining: $14,000).

Year 2-5 (2025-2028): The Carryforward Phase

At the start of 2025, Dakota Ag-Tech has a carryover balance of $14,000 from their 2024 R&D activities.

• 2025: Liability is $5,000. They apply $5,000 of the 2024 carryover. (Remaining: $9,000).
• 2026: Liability is $0 (Loss year). They earn a new credit of $20,000 but cannot use it. The $9,000 from 2024 remains “banked,” and the $20,000 from 2026 begins its own 15-year clock.
• 2027: Liability is $12,000. They must use the oldest credits first.

• They use the remaining $9,000 from 2024.
• They use $3,000 of their 2026 credit to offset the rest of the 2027 liability.

• 2028 Balance: The 2024 credit is fully exhausted. The 2026 credit has $17,000 remaining, which can be carried forward through 2041.

Final Thoughts

The North Dakota Research and Experimental Expenditure Tax Credit provides a robust framework for incentivizing continuous innovation through its flexible carryover provisions. By mandating a three-year carryback and providing a fifteen-year carryforward, N.D.C.C. § 57-38-30.5 acknowledges the inherent risks and long-term timelines associated with industrial R&D. Furthermore, the state’s commitment to providing liquidity through credit transferability for small primary sector businesses demonstrates a sophisticated understanding of the needs of the startup ecosystem.

For North Dakota businesses, the strategic utilization of these credits requires a deep understanding of calculation methods—Regular versus ASC—and a commitment to rigorous documentation. As the state moves toward a more diversified economic future, these tax incentives will continue to serve as a critical bridge between today’s research expenditures and tomorrow’s industrial leadership. Businesses should work closely with the Office of State Tax Commissioner and the Department of Commerce to ensure they are maximizing their earned credits and maintaining the compliance standards necessary to protect their fifteen-year carryforward assets.
